Research progress on microbial degradation of dinitroaniline herbicides

Abstract:

Dinitroaniline herbicides are a class of highly efficient pre-emergence herbicides, with broad spectrum and wide application. Microbial catabolism plays the most important role in the dissipation of the dinitroanilines in the environment. Isolating highly efficient herbicides-degrading microorganisms, studying the metabolic pathways, and elucidating the degradation mechanisms will provide the theoretical basis and degrading resources for the study on the transformation mechanism and ecological security of the herbicides in the environment, and for the microbial remediation of the herbicides residual contamination in the environment. This paper summarizes the research progress on microbial degradation of dinitroaniline herbicides, including degrading bacteria, metabolic pathways, and the genes/enzymes involved in the degrading progress. The aim of this review is to provide theoretical basis and resources for the bioremediation of dinitroaniline herbicides residual contamination in environment.
